DevOps

DevOps is a movement that is closely related to the ideas of Lean Manufacturing. It describes:

A culture of working in a way that combines development and operations, that focuses on the release pipeline
A set of technologies that supplement that work, which pertain to the process of either continuous delivery of code, monitoring or general automation
A mindset that focuses on ubiquitous monitoring, so that short feedback loops can be established, which enable fast development cycles with high reliability while fostering organizational learning
A perspective, that looks at all the (software related) value streams in an organization and seeks to optimize them
